I will be lifting my 2010 larait soon and was wondering if i go with 37's should i worry about burning up my transmission from running stock gears and constantly downshifting when im on the highway. Gas milage to me isnt a problem, i get my gas paid for, but im from Houston and work in Pennsylvania and from time to time drive my truck home. I just wanna see if anyone has exp. any transmission issuse due to running 37's or 38's. Thanks guys
